New York Rangers defenseman Adam Fox is going on injured reserve with an upper-body injury, according to a person with knowledge of the decision. Fox is expected to miss some time but should return before the end of the regular season,

The New York Rangers have reportedly placed Adam Fox on injured reserve. Fox suffered an upper-body injury during the Rangers’ 5-1 victory over the New York Islanders on Tuesday night. He fell hard to the ice and was seen laboring his left shoulder before quickly making his way to the locker room.

The Rangers’ chances of beating out the crowded field vying for a playoff spot will be a little bit more challenging now that they will be without top defenseman Adam Fox, who was placed on injured reserve Wednesday with an upper-body injury. Fox will miss at least a week and perhaps more.
